Qingyou Han, professor of mechanical engineering technology, has devised a way to add titanium powder to aluminum to produce stronger and lighter composite materials for manufacturing. Han received a patent for his work.

A Purdue researcher has patented a process of collecting a small vehicle’s energy in an ultracapacitor through regenerative braking. The lighter ultracapacitor can store energy better and for longer periods than a typical vehicle battery, which makes it ideal for providing additional energy when it is needed most, such as during acceleration.

Two College of Technology professors were among 54 Purdue researchers honored Nov. 20 at the ninth annual Inventors Recognition Reception.

Stephen Elliott and Kyle Lutes were awarded patents during the 2012-13 academic year. Elliott is a professor of technology leadership and innovation, assistant dean for research for the College of Technology and director of the International Center for Biometric Research. Lutes is an associate professor of computer and information technology.
